1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo investigate whether implant-supported overdentures provide nutritional advantages compared with conventional complete dentures in older edentulous adults, through a systematic review and meta-analysis.

methodsA comprehensive search was performed in PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library, EMBASE, LILACS, LIVIVO and grey literature sources. Eligible studies included completely edentulous patients aged ≥ 60 years rehabilitated with overdentures or conventional complete dentures, with nutritional intake assessed using validated methods. Data extraction and risk of bias assessments were conducted independently by calibrated reviewers. Random-effects meta-analyses were performed, and the certainty of evidence was rated using GRADE.

resultsNine studies met the inclusion criteria, of which five were included in the quantitative synthesis. Overdenture users showed significantly higher vitamin B12 levels at 6-month follow-up (SMD = 0.60; 95% CI: 0.18-1.02; I

conclusionWhile overdentures improve masticatory function and may transiently enhance vitamin B12 status, the current body of evidence does not support a consistent nutritional advantage over conventional dentures. High-quality, long-term trials are needed to clarify the systemic nutritional implications of prosthetic rehabilitation in older adults.
